The 7140SA35J8 is a high-speed 1K x 8 dual-port static SRAM from Quarktwin Technology Ltd., designed for asynchronous memory applications. It operates with a maximum access time of 35 ns, making it suitable for commercial applications. The device supports battery backup operation with 2V data retention, specifically in the low-power (LA) version. It is TTL-compatible and requires a single 5V ±10% power supply. The memory is available in various package types, including 48-pin DIP, LCC, and 64-pin TQFP, accommodating different design requirements. The 7140SA35J8 is compliant with military specifications (MIL-PRF-38535 QML), ensuring reliability in demanding environments. It features fully asynchronous operation from either port, allowing independent access for reads and writes. The device also includes on-chip port arbitration logic and a BUSY flag for efficient communication between ports.
